controller_fan: add ability to watch temperature_sensors too

[slaesh]

I searched a way to have a fan controller that just watches one or more temperature sensors.. like host-temperature. since the enclosure fans of my voron are pretty loud.. and I noticed that most of the stuff is not getting hot at all.. so.. having this fan-controller work without the heater/extruder.. and just watch actual temperatures would be awesome! for my ears.. for the fans.. and hopefully for other guys out there ;)

I found this pretty old PR from @mnigbur, which did not make it back then..

just pinging some of the guys who where active in the past in this thread.. @Ramalama2, @theopensourcerer, @meteyou, @edddeduck, @KevinOConnor

question: any chance to test it without running an actual machine? (in general, not for this one =))

To-Do:

• [x] adjust linting (its not linting, its a hand-written code checker :D)
• [x] test on machine

Hey James, I am happy to do that. But I am not sure exactly what to do 🙈 Where do I need to upload that "signed" file? :)

do I need to add another commit with --signoff option?

[slaesh]

oh I see, the link was not working on my github app this morning. so.. we add this sign-off thingy at the squashed commit or how do I add this kind of stuff for the already done commits? Oo

@JamesH1978 done. Just saw another PR which had it in the description text. Hope this does the job ;)

Just a thought, but would the combined temperature sensor and a regular temperature_fan help to achieve a similar result?

Is this not what's already covered with temperature_fan?

You can set a temperature_fan to check an mcu temp.

Example:

[temperature_fan SB2040_Fan] pin: sb2040:gpio15 sensor_mcu: sb2040 sensor_type: temperature_mcu cycle_time: 0.010 hardware_pwm: False min_temp: 0 max_temp: 100 control = pid pid_kp = 59.385 pid_ki = 0.153 pid_kd = 5758.870 min_speed: 0.1 target_temp: 45

Ignore my PID settings, they're horrible. I was messing around.

Seems to me the reason is that you cant have a single fan be both a controller_fan and a temperature_fan.
